The sun is always a spectacle, evolving throughout the day, but when it appears surrounded by trails it seems as if the sky had been decorated with garlands.
We can appreciate this colorful phenomenon in this series of photographs captured in Granollers, in Vallès Oriental, where the sky also acquires an intense orange hue.
This color of the sky is due to the candilazo, a meteorological phenomenon in which the clouds in the sky show a wide palette of colors that ranges from pink to the most intense orange.
As part of the phenomenon of dispersion of sunlight, in the morning and afternoon hours, when the sun is closer to the horizon, the light that reaches the Earth is of soft tones between red and orange.
For their part, the contrails, which could announce a change in weather, have been created by the passage of airplanes, which form a vapor trail after the kerosene combustion process. The gases expelled by the engine come out at a much higher temperature than the outside temperature.
The sharp contrast in temperatures at a height greater than 30,000 feet (-50 degrees in the atmosphere) causes the immediate condensation of the water present in this mixture of substances. This causes us to see these kinds of elongated ice clouds that dissipate after a few seconds.
This phenomenon is known in the Anglo-Saxon and aeronautical world as contrail – a word that comes from the fusion of the words condensation (trail) or in Spanish, condensation trail.
